Ruby-throated Hummingbird migration is in full swing in Tennessee making this an exciting time of year for hummingbird lovers!

The male Ruby-throated Hummingbird shown above is molting feathers, meaning the old worn ones are falling out and being replaced with new ones. Tiny white tubules, that become the feather's shaft, hold the feathers as they grow. Molting during migration is a sign of health, according to Master Bander, Mark Armstrong. It means the hummingbird has enough energy reserves, or fat stored, for both migration and healthy growth.

On Saturday, Aug 22nd, the Knoxville Chapter of the Tennessee Ornithological Society and Ijams Nature Center hosted their fifth annual Wonder of Hummingbirds Festival in Knoxville and the crowd of people attending were enthusiastic and eager to enjoy the many nature activities offered by the festival.

The popular highlight of the event is the hummingbird banding demonstrations offered by Mark Armstrong, Master Bander of hummingbirds and songbirds.

Below, volunteer Andy Troutman removes a male Ruby-throated Hummingbird from one of the bander's traps. Hummingbirds enter the trap to access the feeder and a door is lowered with an attached line.

Once removed from the trap, the hummer is placed in a mesh bag and transported to the bander.

Mark first checks the hummers legs to be sure there is no current band. He then secures a numbered band around its leg and examines the hummer for age, sex and health. Measurements are recorded for the tail and beak and the belly is checked for fat to help determine overall health. If the individual is a juvenile male, he also records the number of red feathers on the throat.

The banding station banded 28 hummingbirds and had one male re-capture that was originally banded at the festival three years ago. The average life-span of a male hummingbird is 1.4 years and the oldest recorded male hummingbird was five years old. Our re-captured bird is doing well!

I was introduced to hummingbird banding in 2009 at the first banding demonstration held at Ijams Nature Center, sponsored by KTOS, and it has been exciting to watch this event expand and attract the large crowds attending today.

For the Love of It...

...the sage sees heaven reflected in Nature as in a mirror, and he pursues this Art, not for the sake of gold or silver, but for the love of the knowledge which it reveals.Sendivogius (1750)

Your Uncapped Creativity...

"There is a vitality, a life force, an energy, a quickening that is translated through you into action; and because there is only one of you in all time, this expression is unique. If you block it, it will never exist through any other medium and it will be lost. The world will not have it. You must keep that channel open. It is not for you to determine how good it is, nor how valuable. Nor how it compares with other expressions. It is for you to keep it yours, clearly and directly." ----the great dancer, Martha Graham

Whooping Cranes

Whooping cranes were on the brink of extinction in the early 1940's with only 15 remaining in the population that migrates from their nesting grounds in Canada to the coast of Texas. Today, after many years of help, this population has reached a record number of 266. In order to safeguard this species, biologists are using an innovative method to imprint captive reared Whooping cranes and teach them to migrate behind ultralight aircraft. In this way, Whooping cranes have been restored to the Eastern flyway and a separate wild migrating population has been established. As more and more people have the privilege of seeing these birds, Whooping cranes have become ambassadors for our wetlands and for all species in need of our assistance. Support our wildlife.
